Introduction: Pain management after coronary artery bypass graft (CABG) surgery remains challenging.

Objective: This study aimed to compare the effects of Ketorolac and Paracetamol on postoperative CABG pain relief.

Method: This double-blind randomized clinical trial study was conducted in Ahvaz, Iran, from September 2018-December 2019. Two consecutive groups of 60 patients undergoing elective on-pump coronary artery bypass graft surgery.

Intervention: The patients were divided into 0.5 mg/kg of ketorolac mg/dl and 10 mg/kg of Paracetamol after surgery for pain management. Primary outcomes were: visual analog pain scale (VAS) at the time point immediately after extubation (baseline) and at 6, 12, 24 and 48 h and the total dose of morphine consumption. Secondary outcomes included the hemodynamic variables, weaning time, chest tube derange, in-hospital mortality and myocardial infarction.

Statistical Analysis: The data were analyzed using SPSS version 22(SPSS, Chicago, IL). The Mann-Whitney U-test was used to compare demographic data, VAS scores, vital signs, and side effects. Repeated measurements were tested within groups using Friedman's ANOVA and the Wilcoxon rank-sum test. Values were expressed as means ± standard deviations. Statistical significance was defined as a p-value < 0.05.

Results: Compared with baseline scores, there were significant declines in VAS scores in both groups throughout the time sequence (P< 0.05). The statistical VAS score was slightly higher in the Paracetamol group at most time points, except for the time of 6 h. However, at 24 and 48 h, the VAS score in group Paracetamol was significantly higher than in group Ketorolac. There were no significant differences between groups about hemodynamic variables.

Conclusion: The efficacy of ketorolac is comparable to that of Paracetamol in postoperative CABG pain relief.

Background And Aims: Renal ischemia-reperfusion occurs in some clinical conditions such as kidney surgery that can leads to acute renal failure. The aim of this study was to investigate the effect of p-coumaric acid (CA) on ischemia reperfusion (I/R) injury.

Methods: Thirty rats were randomly divided into five groups; control, CA (100mg/kg), I/R, propylene glycol (10%)+I/R and CA+I/R, (n=6 each). CA and propylene glycol were administered orally for 2 weeks. Then, the rats were subjected to bilateral renal ischemia for 45min and followed by reperfusion for 24h. All rats were killed and kidney function tests, tissue malondialdehyde and activity of antioxidant enzymes were determined. Histopathological evaluations were also performed. In addition, renal expression of the tumor necrosis factor-α and interleukin-1β were determined using enzyme-linked immunosorbent assay and immunohistochemistry.

Results: CA significantly improved the Cr and BUN levels in CA+I/R group compared to I/R group (p<0.005 and p<0.001, respectively). Reduction of tissue superoxide dismutase, glutathione peroxidase and catalase, were significantly improved by CA (p<0.01, p<0.01 and p<0.05). Treatment with CA also resulted in significant reduction in tissue MDA (p<0.05), TNF-α (p<0.001) and interleukin-1β expression (p<0.001) that were increased by renal I/R. Also, the rats treated with CA had nearly normal structure of the kidney.

Conclusions: The present findings suggest that, CA protects the kidneys against I/R injury via its antioxidant and anti-inflammatory effects.

Risks of on-pump coronary artery bypass grafting surgery in patients with chronic obstructive pulmonary disease due to sulfur mustard.

Sulfur mustard (SM) is a toxic chemical agent that belongs to a class of vesicant compounds. In the 1980s it was used by the Iraqi army against Iranian forces. Sulfur mustard severely irritates the skin, eyes and lungs. The highest side effects seen in patients affected by this gas are pulmonary complications including different types of lung diseases such as bronchiolitis. It has also led to a certain type of chronic obstructive pulmonary disease called mustard lung. Similar extra-pulmonary, molecular and hormonal effects can be observed in these patients and patients with chronic obstructive pulmonary disease. Here cardiovascular complications may be one of the most dangerous visible effects. And atherosclerosis is probable following the direct effects or consequential long-term effects of SM. The development of atherosclerosis in these patients is associated with an increased risk of cardiovascular and coronary artery disease. Coronary artery bypass grafting surgery is the treatment of coronary artery disease. Doing this surgery by bypass pump has its own morbidity and due to local and systemic inflammation changes in patients with SM pulmonary disorders it may have more side effects. Therefore, detailed knowledge of inflammatory diseases as well as the serum level or even the local lung fluid of the inflammatory factors in these patients before surgery are needed so that it would be possible to reduce the rate of morbidity and mortality by normalizing the inflammatory conditions of the patients before cardiac surgery.

A rare presentation of late right coronary artery spasm following aortic valve replacement.

ARYA Atheroscler 2015 Jan;11(1):50-3

Rajaie Cardiovascular Medical and Research Center, Iran University of Medical Sciences, Tehran, Iran.

Background: Coronary artery spasm (CAS) is defined as a reversible, sudden epicardial coronary artery stenosis that causes vessel occlusion or near occlusion.

Case Report: In this article, we present a clinical case of CAS in a 48-year-old woman undergoing elective aortic valve replacement surgery for aortic stenosis. On the 3rd post-operative day, the patient suffered from chest pain and dyspnea. Emergent coronary angiography demonstrated a significant spasm of the ostium portion of the right coronary artery.

Conclusion: This case shows that delayed coronary spasm should be considered as a cause of hemodynamic instability after valvular surgery.
